Elevator system

ABSTRACT

An elevator system including an elevator car having main and auxiliary car stations, each of which include pushbuttons for registering calls for service to various landings of an associated structure. The car calls are stored and serialized in the main and auxiliary car stations, and a single serial car call signal is provided in response to the serial signals from the main and auxiliary car stations. A serial set line is connected to each car station responsive to car calls originating at the other car station, simulating parallel interconnection of the pushbuttons of the two car stations by setting a call on one station which originated at the other station.

1. An elevator system, comprising: a structure having a plurality oflandings, an elevator car mounted for movement relative to saidstructure to serve the landings, car control means including a main carstation and an auxiliary car station disposed in said elevator car,means for registering calls for service to said landings from each ofsaid main and auxiliary car stations, means storing the calls registeredon said main and auxiliary car stations in said elevator car, meansserializing the calls for service registered on said main and auxiliarystations, and serial call set means reyponsive to said serialized callsfor service, providing a serial car call set signal for the main carstation and a serial car call set signal for the auxiliary car stationwhich set a call initiated on one of the car stations on the other ofthe car stations, to simulate parallel interconnection of the means forregistering calls for service from the main and auxiliary car stations.2. The elevator system of claim 1 wherein the means which serializes thecalls for service includes first means for serializing the calls fromthe main car station, second means for serializing the calls from theauxiliary car station, and third means responsive to said first andsecond means providing a single serial signal which includes all callsfor service registered on the main and auxiliary car stations, andwherein the serial call set means is responsive to the single serialsignal provided by said third means to provide like car call set signalsfor the main and auxiliary car stations.
 3. The elevator system of claim2 including means for providing car call set signals from a point remotefrom the elevator car, wherein the third means is responsive to saidremote car call set signals, incorporating the remote car call setsignals into the single serial signal.
 4. The elevator system of claim 1including scan counter means which repetitively counts through apredetermined group of numbers to provide a plurality of timing signalswhich divide repetitive periods of time into a plurality of scan slots,with the landings of the structure being assigned to different scanslots, wherein the means serializing the calls for service places thecalls into the scan slots assigned to the landings they are associatedwith.
 5. The elevator system of claim 4 including means for providingcar call reset signals in the scan slots associated with the landings,and means modifying the serial call set signals provided by the serialcar call set means in response to said reset signals, to eliminate a carcall set signal from a time slot in which a car call reset signalappears.
 6. The elevator system of claim 1 including indicating meanswhich visually indicates calls initiated on each of the main andauxiliary car stations, wherein the serial call set signal when settinga call on one of the stations also actuates its associated indicatingmeans.
 7. The elevator system of claim 1 wherein the means forregistering calls for service from each of the main and auxiliary carstations includes pushbuttons.
 8. The elevator system of claim 1 whereinthe means which serializes the calls for service includes first meansfor serializing the calls from the main car station and second means forserializing the calls from the auxiliary car station, and wherein theserial call set means is responsive to the first and second means toprovide a serial car call set signal for main car station responsive tothe second means and a serial car call set signal for the auxiliary carstation responsive to the first means.
